标题： A functional treatment of small instanton-induced axion potentials

摘要： 我们提出一种功能方法，以完成轴子势的完整单瞬子计算。 这是针对一个$SU(N)$规范理论，其物质内容可以是规范群的任何表示。 这种计算需要表达该理论的费米子零模。 我们为$SU(2)$的所有表示构造它们，这些表示作为构建$SU(N)$的任意表示的费米子零模的构建模块。 该方法应用于最小超对称$SU(5)$模型及其低能对应物，即包含两个颜色三重态的最小超对称标准模型。 显示英文摘要

摘要： We present a functional method to perform complete one-instanton calculations of the axion potential. This is done for an $SU(N)$ gauge theory with a matter content in any representation of the gauge group. This type of computation requires the expression of the fermion zero modes of the theory. We construct them for all representations of $SU(2)$, which serve as building blocks for obtaining the fermion zero modes for arbitrary representations of $SU(N)$. The method is applied to the Minimal Supersymmetric $SU(5)$ model and its low-energy counterpart, the Minimal Supersymmetric Standard Model extended with two color triplets.
